DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Figure 1-3 As shown, the utility model provides a multifunctional quilt cover edge reinforcement device, including a base 1, a central hole 11 is vertically opened in the center of the base 1, side holes 12 are horizontally opened along the side walls of the central hole 11, side bolts 13 are placed inside the side holes 12, and a fixing spring 14 is sleeved around the side bolt 13, one end of the fixing spring 14 away from the central hole 11 contacts the narrow part inside the side hole 12, and one end of the fixing spring 14 close to the central hole 11 contacts the protrusion of the side bolt 13.

[0023] By adopting the above technical solution, the side bolt 13 can move in the side hole 12 , and the fixing spring 14 will push the side bolt 13 to move toward the center hole 11 after being compressed.

[0024] A fixing component 2 is disposed above the base 1 . A central cavity 21 is vertically provided at the center of the fixing component 2 . A fixing shaft 22 is disposed inside the central cavity 21 . The fixing shaft 22 passes through the lower end of the fixing component 2 and extends to the inside of the central hole 11 .

[0025] By adopting the above technical solution, the fixed shaft 22 can move in the middle cavity 21, and the part of the fixed shaft 22 located at the lower end of the fixed component 2 can be inserted into the middle hole 11 and cooperate with the side bolt 13 to install the fixed component 2 on the base 1.

[0026] The part of the fixed shaft 22 located inside the fixed component 2 is sleeved with a return spring 23, the lower end of the return spring 23 contacts the lower end of the fixed component 2, the upper end of the return spring 23 contacts the raised part of the fixed shaft 22, and the upper end of the fixed shaft 22 passes through the upper end of the fixed component 2 and extends to the outside of the fixed component 2.

[0027] By adopting the above technical solution, the return spring 23 will provide an upward force to the fixed shaft 22 after being compressed.

[0028] A semicircular head 221 is provided at the lower end of the fixed shaft 22, a limit block 222 is provided in the middle of the fixed shaft 22, the limit block 222 is located outside the fixed component 2, and a movable ring 24 surrounds the fixed shaft 22, and the movable ring 24 is located between the limit block 222 and the semicircular head 221.

[0029] By adopting the above technical solution, when the fixing component 2 is installed on the base 1, the semicircular head 221 is stuck by the side bolt 13 after passing through the side bolt 13. When the fixing shaft 22 is pressed from top to bottom, the movable ring 24 passes through the side bolt 13 again. When the pressing is released, the reset spring 23 makes the fixing shaft 22 move upward. At this time, the upper surface of the movable ring 24 contacts the side bolt 13 first instead of the semicircular head 221. The shape of the movable ring 24 makes the side bolt 13 move into the side hole 12, and the fixing component 2 can be detached from the base 1.

[0030] The two sides of the outer wall of the fixing component 2 are symmetrically mounted with clamping components 3, the clamping component 3 comprises a clamping body 31, a movable groove 34 is formed on the side wall of the clamping body 31, and a threaded rod 33 is threadedly connected at the center of the top end of the clamping body 31.

[0031] By adopting the above technical solution, the clamping components 3 are symmetrically distributed on both sides of the fixing component 2, and can clamp one corner of two quilt covers at the same time, making it more convenient to splice the quilt covers and reducing gaps.

[0032] The threaded rod 33 passes through the top of the clamp body 31 and extends to the movable piece 35 . The center of the movable piece 35 is rotatably connected to the lower end of the threaded rod 33 . One end of the movable piece 35 close to the side wall of the clamp body 31 is slidably connected to the movable groove 34 .

[0033] By adopting the above technical solution, the threaded rod 33 can rotate to push the movable sheet 35 up or down, thereby achieving a clamping effect.

[0034] The clamping assembly 3 is disposed obliquely, and the clamping assembly 3 opens in an obliquely downward direction.

[0035] The upper surface of the lower end of the clamping assembly 3 is in contact with the lower surface of the movable sheet 35, and the contact portion is roughened.

[0036] By adopting the above technical solution, the clamping component 3 is arranged downward so that the clamped part of the quilt cover can contact the ground, thereby increasing the stability of the clamping. The rough treatment of the clamping component 3 can increase the friction force and make the quilt cover more stable.

[0037] Working principle: When the utility model is in use, a number of bases 1 of the utility model are evenly buried in the ground on both sides of the greenhouse according to the width of the greenhouse quilt cover, so that the upper surface of the base 1 is exposed on the ground. When the quilt cover is to be installed, the fixed shaft of the fixing component 2 is inserted into the middle hole 11 of the base 1, and the semicircular head 221 is stuck by the side bolt 13 after passing through the side bolt 13 to complete the installation of the base 1 and the fixing component 2. Then, one corner of the quilt is placed in the clamping component 3, and the quilt cover is clamped by rotating the threaded rod 33, and then one corner of the other quilt cover is clamped in the other clamping component 3 through the same operation, and then the other side of the quilt cover is clamped in the clamping component 3 on the other side of the greenhouse through the same operation to complete the laying of the greenhouse quilt cover. When the climate changes and the quilt cover needs to be removed, the corners of the quilt cover are loosened by rotating the threaded rod 33, and the quilt cover is folded up. Then, the fixing component 2 and the clamping component 3 can be separated by pressing the top of the fixed shaft 22 of the fixing component to complete the disassembly.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
